Previous vibration models were based on continuum beam theories, which could not take into account the porous property of the concrete beam. This paper adopts a two-scale fractal vibration model, and its low frequency property is revealed. This new finding can explain the vibration attenuation and vibration absorption of the porous concrete, and the present theory sheds a new light on the concrete design.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A7465638">Cited in <strong>17</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A74H45" title="MSC2020">74H45</a> </td> <td class="space"> Vibrations in dynamical problems in solid mechanics </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A74K10" title="MSC2020">74K10</a> </td> <td class="space"> Rods (beams, columns, shafts, arches, rings, etc.) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A74F10" title="MSC2020">74F10</a> </td> <td class="space"> Fluid-solid interactions (including aero- and hydro-elasticity, porosity, etc.) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A74H10" title="MSC2020">74H10</a> </td> <td class="space"> Analytic approximation of solutions (perturbation methods, asymptotic methods, series, etc.) of dynamical problems in solid mechanics </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A28A80" title="MSC2020">28A80</a> </td> <td class="space"> Fractals </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3ABernoulli-Euler+porous+beam+model">Bernoulli-Euler porous beam model</a>; <a href="/?q=ut%3Avibration+attenuation">vibration attenuation</a>; <a href="/?q=ut%3Atwo-scale+fractal+derivative">two-scale fractal derivative</a>; <a href="/?q=ut%3Afractal+oscillator">fractal oscillator</a>; <a href="/?q=ut%3Avariational+principle">variational principle</a>; <a href="/?q=ut%3Ahomotopy+perturbation+method">homotopy perturbation method</a>; <a href="/?q=ut%3Aperiodic+solution">periodic solution</a>; <a href="/?q=ut%3Aresonance">resonance</a></div> <!-- Modal used to show zbmath metadata in different output formats--> <div class="modal fade" id="metadataModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">Cite</h4> </div> <div class="modal-body"> <div class="form-group"> <label for="select-output" class="control-label">Format</label> <select id="select-output" class="form-control" aria-label="Select Metadata format"></select> </div> <div class="form-group"> <label for="metadataText" class="control-label">Result</label> <textarea class="form-control" id="metadataText" rows="10" style="min-width: 100%;max-width: 100%"></textarea> </div> <div id="metadata-alert" class="alert alert-danger" role="alert" style="display: none;"> <!-- alert for connection errors etc --> </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary" onclick="copyMetadata()">Copy to clipboard</button> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <div class="functions clearfix"> <div class="function"> <!-- Button trigger metadata modal --> <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 1482.74083" data-ciurl="/ci/07465638" data-biburl="/bibtex/07465638.bib" data-amsurl="/amsrefs/07465638.bib" data-xmlurl="/xml/07465638.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/07465638.pdf" title="Zbl 1482.74083 as PDF">Review PDF</a> </div> <div class="fulltexts"> <span class="fulltext">Full Text:</span> <a class="btn btn-default btn-xs" type="button" href="https://doi.org/10.1142/S0218348X21501176" aria-label="DOI for “Low frequency property of a fractal vibration model for a concrete beam”" title="10.1142/S0218348X21501176">DOI</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">Kalfat, R., Al-Mahaidi, R. and Smith, S.
